ARMS40L-SP: A.R.M.S. #40L
SP SAME PLANE LOW PROFILE FLIP UP REAR SIGHT - AR15 BUIS Rear Sight - Same Plane
ARMS #40L SP Spring Loaded Rear BUIS for the AR15/M16 flat top family of
rifles that is easily operated with bulky gloved hands. The Same Plane
Aperture deploys either aperture zeroed at the same mark. No worries about
range zero changes when switching from small and large CQB apertures. The A.R.M.S.® #40L
SP Low Profile Flip-up rear BUIS sight is designed to be a co-witness
backup sight that can deploy in a split second when optics have failed. With a
miniaturized windage knob and low mounting height, this ARMS BUIS is ideal for
mounting behind or underneath riflescopes or the EOTech HWS and other red-dot
sights. The A.R.M.S. sight is held in the locked down
position by a quick release lever, that can be deployed with the flip of your
finger. Initial elevation zero is acquired by adjusting the standard M16A2/M4 front sight
post.
The newly designed 250-300 meter Dual Leaf Aperture and smaller miniature
windage dial design allow the A.R.M.S.
Low Profile #40L SP spring loaded flip-up rear BUIS sight to sit nearly flush
with the top rail when mounted behind an A.R.M.S. base riser.
